Held in a 96,000-square-foot warehouse (333 Lancaster St., Oakland) with seventeen departments featuring items such as clothing, furniture, jewelry, antiques, sporting goods, art, and electronics, the White Elephant Sale is not your average garage sale. The event began in 1959 as a way to generate funds for the creation of the Oakland Museum of California, and 55 years later, it remains the museum’s biggest fundraiser, as well as Northern California’s largest rummage sale. Last year, the event raised $1.8 million. The goods, which are all donated, can run the gamut from high-end merchandise to bargain tchotchkes. This year, collections of vinyl records, comic books, and train sets will be among the items being sold. According to organizers, some shoppers buy their wardrobes for the entire year at the sale, as well as wedding dresses, engagement rings, and costumes for Bay to Breakers. Be prepared for a crowd — lines to enter usually go down the block.
